Infarct ratios and edema ratios measured 24 hours after cerebral ischemia/reperfusion injury. An infarct ratio was calculated as the percentage of the size of the infarcted tissue area with reference to the size of the ipsilateral hemisphere. Each edema ratio was calculated as the percentage of the size of the ischemic hemisphere with reference to that of the contralateral normal hemisphere. The boxes show interquartile ranges; the thick lines are medians and the error bars are the 10th and 90th percentiles. ^*P < 0.05 compared with the saline group. ◦: Extreme examples of over three-fold each box value. CG: saline treated control group, 0.1 GG: 0.1 mg/kg gabapentin group, 0.5 GG: 0.5 mg/kg gabapentin group, 5 GG: 5 mg/kg gabapentin group.
